. COMBINATION BRAKE-BEAM GUIDE AND SAFETY-GUARD.

Application filed July 11, 1919. Serial N0. 310,146.

T 0 all whom it may concern:

Be it known that I JOHN L. MOHUN, a citizen of the United tates, residing at the city of New York, in the State of New York, have invented a certain new and useful Improvement in Combination Brake-Beam Guides and Safety-Guards, of which the following is a full, clear, and exact description, such as will enable others Skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevational view of my improved combination brake beam guide and safety guard. I

Fig. 2 is a similar view of a modified form.

Fig. 3 is a similar view of amodified form, and 4 Fig. 3 is a similar view of another modified form.

This invention relates to a new and useful improvement in combination brake beam guide and safety guard, the object being to apply a device of the character described to a car truck without employing any special means of attachment to the truck.

My improvement consists in a frame' which extends across a spring plank and is supported by the brake beams in such a way that it forms a guide for the beams when they are being applied to the wheels and also a support for the beams in the event of failure of the brake hangers, brake levers or other brake beam supports.

In Fig. 1, I have shown one form of my invention in which 1 indicates the spring plank and 2 the bolster of an ordinary truck, 3 are the wheels and 4 the axles of the truck. 5 indicates brake beams which are suspended by theusual hangers (not shown),

said brake beams consisting of compression.

members 6 and tension members 7 In Fig. 1, 8 indicates a casting extending across and over the spring plank 1 having nose extensions 8 which rest upon the compression members of the brake beam, said casting having underhung extensions 8 spaced apart from the nose portions 8 so as to accommodate the compression members 6 of the brake beams. These extensions 8 are preferably I-shape in cross section so as to provide tracks on which castings 9 having Patented Nov. 2, 1920.

lips at their outer extremities which engage theltop flange of the I-shaped portion 8 and constitute a support for a tension member of the brake beam. Retaining guides 1 earned by spring plank 1 prevent the lateral movement of casting 8. a

In Fig. 2, I have shown an underhung casting 10 which is provided with reentrant overhanging ends 10 extending over the sprlng'plank, which reentrant overhanging portions provide spaces for receiving the compression members 6 of the brake beam, and which compression members support the castlng 10. 11 indicates springs carried by the casting 10, whose outer ends embrace the tension member 7 of the brake beams so as to retract them when released. Retaining guide 1 carried by spring plank 1 prevents the lateral movement of casting 10. 1

In Fig. 3, I have shown a plate or builtup structure in which 12 indicates a member extending across the spring plank 1, and whose outer end is bent to provide a track 12 for a wear shoe 13 carried by the tension member 7 of the brake beam, of which 6* represents the compression member. There is a bent plate 14 secured to the plate 12 so as to extend under the compression member 6 and arubbing plate 15 is arranged on the sprin plank 1 to serve as a chafingsurface.

In ig. 3*, I have reversed the plate arrangement in making the plate 12 straight and extending the under plate 12 secured thereto outwardly so as to provide a track for a shoe 13 .on the tension member 7 of the brake beam of which 6? represents the compression member.

In all forms of my invention, it will be noted that the compression members of the brake beams on each side of the spring plank constitute the supports for a member which serves to guide the brake beam,
